Underpinning the Role of Nanofiltration and Other Desalination Technologies for Water Remediation and Brine Valorization: Mechanism and Challenges for Waste‐to‐Wealth Approach

open access: yesAdvanced Energy and Sustainability Research, Volume 5, Issue 11, November 2024.
Desalination brine poses several environmental risks, but resource recovery from brine offers both mitigation and revenue potential. Growing demand for secure mineral sources and sustainability drives the development of technologies like reverse osmosis, electrodialysis, and distillation to recover valuable materials.

Material availability assessment using system dynamics: The case of tellurium

open access: yesProgress in Photovoltaics: Research and Applications, Volume 32, Issue 4, Page 253-266, April 2024.
System dynamics is used to assess the availability of tellurium for CdTe PV. Results show that increasing the CdTe PV manufacturing capacity is insufficient if tellurium is unavailable. Expanding existing Te‐rich ores does not alleviate tellurium scarcity while improving tellurium yield from copper electrorefining is a more efficient mitigation ...

Effect of Solution Composition on the Passivation of Anode in Copper Electrorefining

open access: yesJournal of MMIJ, 2017
To elucidate the effect of solution composition on the passivation of anode in Cu electrorefining, the potentiodynamic polarization curves were measured by polarizing from -0.2 V versus NHE to 1.0 V using the potential sweep method at 1.0 mV·s−1.
